Vortica II Blower

The Vortica II Blower is exclusively available from Trane. It’s designed to distribute air flow through your home as quietly as possible – described as a “whisper” by Trane themselves. The Vortica II blower is also one of the most efficient blowers available in the industry and is one of the reasons this unit achieved the impressive AFUE rating of 96%.

Comfort-R Technology

Comfort-R technology is an additional feature that helps you control the humidity levels in your home to ensure you’re as comfortable as possible. It also allows for the furnace to start-up and shutdown in such a way that lowers the decibel level, meaning it’s as quiet as possible, improves energy efficiency and allows for a more thorough circulation of heat around your home.

Self-Diagnostic Microelectronic Control

The self-diagnostic microelectronic control that’s incorporated into this furnace monitors the status of the unit to diagnose any faults or problems and help an engineer service the furnace should any problems arise.

Other Key Features

• Silicon Nitride Hot Surface Igniter
• Certified to be airtight to less than 1%

Warranty Information

The S9V2 comes protected by some fairly standard warranty options – a lifetime heat exchanger limited warranty and a 10-year parts limited warranty. However, make sure you register your unit either online or via phone within 60 days of purchase or these warranty periods are subject to change.

Comparable Models by Trane

Model comparison by lower price – Trane S9V2 versus Trane XR95

If you’re looking for a lower priced unit than the S9V2, an option is the XR95. Although both of the AFUE ratings for the S9V2 and XR95 are similar at approximately 95%, you lose some key features on your furnace. For example, the S9V2 has Trane’s very own Vortica II blower, which is designed to operate extremely quietly and efficiently. You also lose the Comfort-R technology built into the S9V2. In terms of build, the XR95 is not certified to be airtight to 1% like the S9V2 and has a single-stage operation as opposed to the S9V2’s two-stage operation.

Model comparison by features – Trane S9V2 versus Trane XR95

The S9V2 and the XR95 are very similar in terms of their efficiency, boasting a 96% and a 95-96.7 AFUE rating respectively. However, they both feature some different technology. For example, the S9V2 includes the Vortica II Blower for quieter operation. The S9V2 also includes an impressive secondary heat exchanger which can extract even more heat from the combustion process thanks to its corrosion resistant 29-4C stainless steel. Nevertheless, both are equipped with Comfort-R technology and are made with durable materials. This one will come down to personal preference on features for the buyer.
